wheeler: ants collected in Grenada, w. r. 171 



Camponotinae. 



21. Prenolepis longicornis Fabr. — Several workers from Richmond 

 Hill. 



22. Camponotus abdominaUs Fabr. subsp. nocens, subsp. no v. 

 Worker major. Length 10-11 mm. 



Mandibles shining, finely striated and coarsely and sparsely punc- 

 tate; head opaque, finely and densely punctate, slightly shining on 

 the sides and in front. Elongated foveolae on the cheeks small and 

 not abundant. Thorax, petiole, gaster and legs shining; gaster very 

 finely and transversely shagreened. Antennal scapes subopaque. 



Hairs fulvous, long, erect, but much less abundant than in the 

 typical abdominaUs, confined to the vertex, clypeus, gula, mandibles, 

 thoracic dorsum, border of petiole, surface of gaster and fore coxae. 

 There are a few scattered, suberect hairs on the flexor surfaces of the 

 femora and a few (less than half a dozen) on the extensor surface of 

 each tibia. Pubescence yellow, very sparse, most distinct on the 

 gaster, cheeks and antennal scapes. 



Rich yellow; head, antennae and tarsi red, with the vertex and 

 mesial portions of the cheeks brown; mandibular teeth, corners of 

 clypeus, anterior borders of cheeks and apical two-thirds of antennal 

 scapes black; posterior half of first gastric segment and the whole 

 of the remaining segments, except their posterior margins and some- 

 times portions of the venter, dark brown. 



Worker minor. Length 6-7 mm. 



Like the worker major, except that the head is more shining, the 

 antennal scapes are not blackened and nearly the whole of the first 

 gastric segment is yellow. The head is subrectangular, broad behind 

 the eyes, with straight posterior border and distinct posterior corners. 



Female (dealated). Length 14-15 mm. 



Resembling the worker major. Head narrower, with straight, 

 anteriorly converging sides, sharp posterior corners and straight 

 posterior border. Thorax and gaster more glabrous and shining; 

 otherwise the sculpture, color and pilosity are like those of the worker 

 major. The mesonotum has a faint brown anteromedian and two 

 lateral spots. The border of the petiole is rather deeply notched in 

 the middle. 



Described from two females and a number of workers taken from 

 rotten logs at Grand Etang and Richmond Hill. 



The vivid coloration and feeble pilosity place this form in the group
